I have Slackware 13.1 with kernel 2.6.37. Everything is working fine, except that I can't mount any CD/DVD and automount is not working either. If I connect any USb to my laptop it doesn't automount, I need to manually mount it. The same case happens with CD/DVD only that I can't mount any CD/DVD even manually. Here's the output:
Code:
bash-4.1# mount /dev/cdrom /mnt/cdrom
mount: block device /dev/sr0 is write-protected, mounting read-only
mount: you must specify the filesystem type
bash-4.1# mount /dev/cdrom /mnt/cdrom -t iso9660
mount: block device /dev/sr0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
Reading kernel messages with tail shows:
Code:
Jan 10 17:10:50 marian kernel: VFS: Can't find a valid FAT filesystem on dev sr0.
Jan 10 17:10:57 marian kernel: attempt to access beyond end of device
Jan 10 17:10:57 marian kernel: sr0: rw=0, want=68, limit=4
All dmesg??? cause is very long. Will post here was relevant to /dev/sr0 and cdrom stuff found from Dmesg.

Is an Office 2003 Disc, I also try it with Slackware install CD (the same one I use to install it here at my laptop) and I still get the same message .... I don't know where to start, the Office 2003 CD works fine under any laptop that has Windows XP or some Window branch. My problem here at Slackware, is that 'automount' doesn't work (not even with USB) and I'm trying to mount CD manually and it doesn't let me.
No :-( it has never work (not even with the kernel that came with Slack 13.1) I even change the CD/DVD device thinking that maybe the problem was the device... is not unfortunately :-(
If I run k3b I'm able to see the device there but empty (without any CD even if there a CD inside the device). Dunno what's happening here, or where to start to check or something.
I don't want to install Office 2003, I just want to open or read any CD that I insert at my CD/DVD device, which Slackware isn't allowing me to do .
No, my user wasn't member of plugdev group, but I have add it now, same as with root, I have restart haldaemon and still get the same error here...how can I fix this issue with hald? can someone give me tips?
PD: I have reboot after adding user and root to plugdev and haldaemon group, and now when I try to mount the CD the prompt stays there and doesn't mount nothing:
bash-4.1$ mount /mnt/cdrom
Also tail -f /var/log/messages shows nothing about this issue... will try to reboot using stock kernel and see..
The same thing even with stock kernel... I try to mount manually the CD no avail, I try to run k3b and it hangs..... this is what ps -aux says about it:
Quote:
root 2147 0.0 0.0 2504 844 ? D 22:32 0:00 mount /mnt/cdrom
marian 2182 0.1 1.3 107360 20584 ? D 22:40 0:00 /usr/bin/k3b
both proccess mount and k3b are TASK_UNINTERRUPTABLE maybe this is a kernel, but both kernels? or a haldaemon problem, I don't know.

it doesn't matter which CD/DVD I use, the results are the same, I'm trying with stock kernel and still get the same. It didn't hang before, it starts to hang after I added my user and root to plugdev and haldaemon group. Before I added both users to those groups, I just wasn't able to mount any CD/DVD now after, it just hangs... and no messages about any error at /var/log/messages. Could it be some haldaemon bug or something?
Can anybody tell me if there have to be some file at /etc/hal/fdi ? I'm asking because I have enter to /etc/hal/fdi/policy , /etc/hal/fdi/preprobe and /etc/hal/fdi/information and all of them are empty, no rules no nothing... is this is ok???
